Hi, All my 4 testers (I have 4 machines running several Mingw targets) are always failing pulling new versions from GitHub. This problem started some days ago. I've tried to reset all machines, network equipment, disabling antivirus, firewall, modified http attributes, modified the regression script to use git protocol instead of https, etc. with no luck. I'm using Windows machines with official Git. Any clue on what's going on? Maybe Github recently does not like so many submodules? Example of failure (several libraries can fail during "git pull "--recurse-submodules""): ------------------- ------------------- ------------------- Fetching submodule libs/io fatal: unable to access 'https://github.com/boostorg/io.git/': OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 10054 Then: # git_source_checkout failed with message "GIT command "git pull "--recurse-submodules"" failed with code 1" # Retrying (5 more attempts). # Executing GIT command: c:\boost\develop\boost_root> git submodule foreach "git submodule deinit ." ------------------- ------------------- All retries fail and the script fails with error: ------------------- ------------------- ------------------- # git_source_checkout failed with message "GIT command "git pull "--recurse-submodules"" failed with code 1" # Giving up.

Anyone else having these problems? I've attached the log of one failure in case someone can see any clue. I really don't see how to solve this, so I won't be able to run regressions. Best, Ion
